This document introduces the features of the Agilent 34970A Data Acquisition/Switch Unit, including price and performance advantages, usage scenarios, functional features, and customizable modules.
The Agilent 34970A Data Acquisition/Switch Unit combines a high‑performance 6½‑digit DMM with modular switching capability in a compact 3‑slot mainframe. It offers up to 120 single‑ended channels or 96 matrix crosspoints, built‑in GPIB and RS‑232 interfaces, and non‑volatile memory for 50 000 readings. The unit supports temperature, voltage, resistance, current, frequency and period measurements, each configurable per channel.
A range of plug‑in modules (multiplexers, actuator, matrix, RF, and multifunction) lets users tailor the system for data‑logging, automated test equipment (ATE), or pure signal routing. Agilent BenchLink Data Logger 3 software is included for PC‑based configuration, real‑time display, and analysis, while drivers are available for Agilent VEE and National Instruments LabVIEW.
